About this work
The channel form at the top of this VIS image is part of Tiu Valles. The impact crater has affected the course of the channel, as has the small hill at the top of the image. This type of feature, a hill with a teardrop shaped section, is called a streamline island. The hill interrupts the fluid flow, creating eddies on the downstream side where the flow velocity lessens and it is unable to erode as easily as in the main part of the channel. The teardrop points downstream.
